SIGNALING-TORPEDO.

Toiall whom it may concern:

Be it known that I,'WILLIAM T. MCCUL- Louon, a. citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Signaling-Torpedoes, of which the ifollowing-is a. specification.

This invention relates to signaling torpedoes, and particularly to that ty e. 2f to}:-

or t e An olajeet of the invention is to provide a' torpe o for this purpose havingmeans thereon adapted to be engaged by the wheel ex losive charge and thereb -hold the torpedb in place and prevent t awheel from shifting the explosive chargetOP'a position where it will not be 61 further: ject of the invention is torovide a method by which the torpedo may.- eaaiiyandircheaply made, withJa mini mumwaste oft-material, the tor do.having for! parts which can be quickly and cheapl ,firmed and assembled. In t idrawings, which illustrate my in- Figured-is anisometric view of a track rail showing a torpedo constructed in acwith my invention applied thereto. Figsfliie a gross sectional vlew'of a torpedo ofwtlae form shown in Fig. 1.

V lll f bl di (1 sh d are so am reera y amonape s shown an it is preferabl formed of "a le iece of material 5. I prefer that thebo y be made of moisture proof fibrous material, though any suitable material can be used. The blank, shown in Fig.

4, is in the form of two diamond shaped paralleiograms 6 and 7, having a common Q side, of the same size. The shape of the the web; and 3 the head of: torpedo is in the form of a Specification of Reissued Letters Patent. Reissued 10; 1921 original Io. 1,337,240, dated April 90, 1920, Serial no. 219,222, filed February 2c, 1918.

blank is such that when it is bent along the Application for i common side, indicated by the dotted line in Fig. 4, section or art 6 will lie over part 7, and the sides 0 6 will coincide with the corresponding sides of 7. Blanks of this shape can be readily formed from sheets or strips of material, with a minimum waste.

A pocket 8 is provided in the member 6, i

which pocket may be formed with a seat 9 around its periphery. The member 6 may also be provided with slots 10 near the edge thereof for the purpose hereinafter described.

' After the blank has" been formed, as shown in Fig. 4, an explosive charge is placedin the pocket 8, and when a seat 9 is provided,

engaging strips 12 are then preferably assed through slots 10, these strips being ormed of soft metal or other suitable material, and have transversely-extending head 'plortion's 13".to prevent the retaining strips om pulling out.

'After the charge has been placed in the pocket 8', and the retaining strips 12, when f-Of the kind just described are employed, arepositioned, the blank is folded propei'l along t common side, indicated in dotted lines in Fig. 4, so that part 6 is superinr sed over part 7, the edges of'the adjacent 5 aces be coated with a moisture proof afiin. When folded and sealed, body is over part 7, and part forms the meansfor preventing displacement of the charge and of the disk 11, while the outside The bod torpedo is diamond shaped, as s own in Fig. 1, and is preferably longer than it is wide. The rail engaging strips 12 are bent downwardly toengage the si head 3. Y By reference to Fig.

es of the rail end sections extend iniadvance of--the ex plosive ehargerand, flat, they are not liable to he s id or pu ed to one side so that the wheel will ride over them. When the wheel is on the piointed extensions, the bod of the to 0 will be clam ed to the rai and'the exp osive char e will held against displacement by t e wheel.
